100 Keysight CXG, EXG, and MXG X-Series Signal Generators Service Guide
Service and Utility Menus
Boot Service Menu
When the instrument boots up in firmware recovery mode the display will
appear as shown in Figure 5-2. At this point the instrument firmware can be
loaded.
If selected by accident, reboot the instrument to return it to normal operation.
Use this feature if the normal instrument firmware installation process will not
work. See Chapter 19, “Instrument Firmware and Operating System” for
information on where to download and how to reinstall the instrument
firmware.
Figure 5-2 Service Boot Menu
Start main firmware service menu
Loads a menu that will allow access to other service related functions. See
“Main Firmware Service Menu” later in this chapter for details.
Scan disks for errors
Loads a menu for selecting what disks to scan and repair.
Format SSD
This will format the A4 Solid State Disk Drive in N5166B, N5172B, and N5182B
instruments. The A4 disk drive contains both user files and files required by the
instrument for certain functionality, and this utility will delete all of them. If this
is used the instrument firmware will need to be reinstalled to recover full
operation to the instrument.
When the instrument is restarted after performing this format the following
errors may be seen:
-315, Configuration memory lost; Persistent state checksum is bad. Using
factory defaults.
-256, File name not found; /USER/USERFLAT/LAST
Both the Format SSD and Format SD Card functions will not ask for a
confirmation of formatting once selected. Be sure this is the desired
function before selecting it.
